Abstract

Procédé de fabrication d'un dispositif électrochrome. On dépose, par évaporation, des couches de WO3 et de MgF2 intercalees entre deux couches conductrices, et on contrôle les pressions d'évaporation de WO3 et MgF 2 pour régler les performances du dispositif. Application à la réalisation de dispositifs d'affichage.Method of manufacturing an electrochromic device. Layers of WO3 and MgF2 interposed between two conductive layers are deposited by evaporation, and the evaporation pressures of WO3 and MgF 2 are controlled to adjust the performance of the device. Application to the production of display devices.
